After anal sex and obtaining a "Poop noodle" (getting a chunk of poop stuck in your penis hole), you then "dock" (The act of placing the head of ones penis inside the foreskin of another's penis) with another man and shoot your poop noodle into the penis hole of the other man.

"That 2nd guy I banged at the party last night had no idea I had just had anal sex with someone else in the closet right before I fucked him in the bathroom. As soon as we started hooking up we started to dock, but unbeknownst to him I was actually docking the space noodle! You should have seen his expression when it popped out with his cum later on all over my face! Oh well, it's classic when you're a sacktapper from dirty Jersey."
